Hey guys, how goes it. I have a 1985 Chevrolet S10 with a carbureted 2.8 V6. It already has an insulator gasket that goes between the carb and the intake manifold with a heated grid attached to it (probably an 1/8-1/4" thick or something) stock. I have heard of people using spacers between their TBI and intake manifolds, but also with carburetors to get a better fuel mixture. I was wondering if anyone thinks it would make a difference (good or bad) if I place a spacer on top of the EFE Insulator gasket to raise the carb even higher from the intake manifold. The spacer would basically be a insulator gasket w/o the heated grid since I have one just sitting here. I have a body lift, so hood clearance isn't an issue.

i've heard both good and bad but the bottom line is you cant tell till you try it. esp with the help of a dyno. most of the ones i've seen people use have the ones with four holes in them. good for top end usually. if you can get one free i'd at least try it. but i wouldnt buy one unless you knew for sure with your engine and how you drive it will help

That's true Bullheimer. I think I might as well go ahead and give it a try. I know it won't make any difference (maybe a tenth in gas mileage and no improvement in throttle repsonse), but it couldn't make this damn 2.8 run any worse:) Thanks for the reply.
